What is a Sinkhole?


Sinkholes are holes in the ground resulting from different types of a lack of support underground. Scientist have identified different varieties of sinkholes, each caused by different forms of underground wear or manmade interference, however all types of sinkholes can severely destroy your property if you’re unfortunate enough to have a home above them. This natural problem may grow from a few feet to almost a mile wide and occur mainly in regions with layers of permeable limestone below. Fortunately, Paul Davis of Hernando can be on call to fix your home after the devastation and fortify your home to avoid problems from developing before a sinkhole hits.

Types of Sinkholes

  • Dissolution Sinkholes – These sinkholes develop when erosion from wind and surface water wears down limestone bedrock. As the top layer of soil recedes, the cover of rock becomes weakened and creates a sunken hole below your property.
  • Cover-collapse Sinkholes – This variety of sinkhole develops in only a few hours and can be catastrophic. Cover-collapse sinkholes happen when the ground cover consists of more clay than sand. With enough time, water and wind can wear down the surface and cause a domed depression just below the surface. If the space between the surface and the underground hole becomes big enough, the sinkhole increases and takes down any object nearby.
  • Cover-subsidence Sinkholes – If the surface above bedrock consists of larger amounts of sand than clay, these sinkholes can occur. Sand can filter and grow underground, resulting in little holes along the surface. Cover-subsidence sinkholes can go unnoticed for long periods of time, but gradually create damage to your home.

Effects of Sinkholes

Sinkholes are most common in regions based in limestone, like the Southern and Eastern United States, especially states like Florida. Depending on the scale of the hole, your property can be dealt severe damage to total destruction. The largest sinkholes have been known to swallow entire buildings and vehicles in one gulp. Lesser specimens are significantly less serious, but can still deal serious damage to your home.

Most often, sinkholes cause damage to pavement and back or front yards. This incident can leave large holes in your home and bring up dirt on your lawn. Sinkholes may also stir up poisonous chemicals below the surface that pollutes tap water. If the sinkhole develops under your property, it can cause building and cause cracks in the base and windows.

Signs of Sinkholes

Sinkholes of any scale can be hazardous to your home. By making the ground uneven, your home endures more stress to stay upright.

After years of neglect, the stress from these sinkholes can crack or even collapse your home’s foundation. Depending on the type, sinkholes can be subtle and expand over decades. Look for the warnings of a sinkhole and act quickly to avoid worse hazards. Keep an eye out for
